How it works
- 1
Choose your files
Pick images or PDFs from your device, or drag them onto the page. The tool checks each file and tells you at once if something is wrong.
- 2
Set it up
Put the files in order and choose the options that matter, such as page size for images or the page range to extract from a PDF.
- 3
Download the result
The new PDF, or a ZIP when several files are created, is built on your device. Save it, open it and check it before you send it.
Why local processing matters
Documents are often private: an identity card, a signed form, a medical letter. When a tool runs in your browser, that file never has to travel to a server to be turned into a PDF. You also avoid upload waits and daily limits, and the tools keep working after the page has loaded even if your connection is slow.
We are straightforward about trade-offs. Everything depends on your device memory, so very large files can fail on a phone. Compression is limited (it shrinks images or flattens pages, and cannot guarantee a size), and there is no text recognition or password removal.

Frequently asked questions
Are my files uploaded to a server?
No. The tools read your files in your browser, process them in your device's memory and hand the result back as a download. The files are not sent to our servers. Closing or refreshing the tab discards them. The page itself can load advertising and optional analytics scripts, but your file contents are not part of those requests.
Do I need an account or to pay?
No account, no signup and no payment. The site is free to use and is supported by advertising where ads are enabled.
Which file types can I use?
Image to PDF accepts JPG, PNG and WebP images. JPG to PDF accepts JPEG photos. Merge PDF and Split PDF accept ordinary PDF files. The tools check the first bytes of each file, so a renamed file of the wrong type is rejected with a message.
What are the size limits?
Image tools take up to 50 files of up to 50 MB each, 200 MB in total. Merge PDF takes 2 to 20 files with the same size caps. Split PDF takes one PDF of up to 50 MB and 500 pages. Phones and older computers may cope with less because everything runs in local memory.
Can you compress a PDF, run OCR or remove a password?
Partly. The Compress PDF tool can shrink the JPEG images inside a PDF, or flatten pages into pictures to aim for a size, but it cannot promise a result and flattening removes selectable text. The site does not offer text recognition (OCR), password removal, editing or signing. The other tools convert images, merge PDFs and split PDFs.
Why was my PDF rejected as encrypted?
Password-protected or encrypted PDFs cannot be read by the merge and split tools. If you own the document and know the password, open it in a PDF viewer and save an unprotected copy, then try again. The guide on fixing common PDF errors walks through this.
